The only way to describe this album is to combine the music of The Beatles with the humor of "Weird Al" Yankovic.
The songs on this album are the same great Who rock tunes you're used to... but with a little bit of humor injected. They put this album together to make it sound like a pirate radio station, complete with fake commercials after some tracks.
Who can resist "The Hall of the Mountain King", a rock instrumental of the classic song where the sound effects begin sounding positively evil with evil-sounding chuckles and screams, then fall into the "silly" category with burps and animal noises. Or "Tattoo", a song about brothers who want to "prove their manliness" by getting tattoos. Or "Odorono", a deodorant commerical song. Yes, deodorant.
On the serious side, there are some of The Who's best songs, including Mary Anne With The Shaky Hand, I Can See For Miles, Silas Stingy, I Can See For Miles, Early Morning Cold Taxi and Armenia City In The Sky.
One of the best albums I've ever heard.
